I was watching “Dr. No” a day or two ago. I happened to notice a 747. That movie had to have been made in the early 60s.
Those planes have been around forever.
Boeing 707
Dr. No - 1962
B-747 - First flight 1969. Entered service, January 1970.
The biggest plane of that era would probably be the VC-10, but it didn’t have its first flight until the end of June, 1962.
